Flange broken




Review of Mike Diamond Plumbing, Inc.

Having my floor replaced and the flange to my toilet was broken. Roots were under the flange and broke it. Bryan and Matt came out and looked at it, they were able to give me a senior discount and when the manager came out e discounted it even more. The job was completed working the expected time frame and the flooring can continue as scheduled. I Couldn’t have asked for a finer group of guys to come do the job.


AC unit fan repaired properly




Review of Mike Diamond Plumbing, Inc.

Yesterday I noticed the fan to my ac unit stopped working suddenly. I've done a lot of business with Mike Diamond. And again it was a good decision. Always happy to do business with them. Thank you Cesar and Bryan. And if course Mike Diamond.

AC unit recommended repair by Cesar




Review of Mike Diamond Plumbing, Inc.

Cesar came out this morning and assessed my AC unit. He was very knowledgeable and explained in detail the issues I had with my AC unit. As soon as I can I will call to get the work done by Cesar. Thank you.


Cesar helped a lot




Review of Mike Diamond Plumbing, Inc.

Cesar unclogged my kitchen and laundry drain with a bigger cable that was cheaper than doing a hydroblast inside the drain pipe. I own a Pool company C52. My guys tried to unclogge it but cesar did it very. Happy we ll stick to pool services and stay away from residential plumbing
